Maximizing Microsoft Sentinel ROI with VirtualMetric DataStream – Part 2 Microsoft Sentinel is an extremely powerful platform—but at scale, Windows telemetry (especially Security events) can quickly become one of the highest cost and noise drivers in the workspace. If you’re already centralizing Windows logs with Windows Event Forwarding (WEF) into a Windows Event Collector (WEC), you’ve already solved half the problem: you’ve reduced agent sprawl and built a clean collection pattern.

🎯 New blog: Maximizing Microsoft Sentinel ROI with VirtualMetric DataStream – Part 2 is live.

This part goes hands-on with WEF/WEC + Windows Event Logs + Microsoft Sentinel using #VirtualMetric #DataStream.
